[0063] FIG. 2 is a block diagram illustrating an acoustic device according to an embodiment of the disclosure.

[0064] Referring to FIG. 2, an acoustic device 200 may be a part or the entirety of the electronic device 101 of FIG. 1. For example, the processor 220 (e.g., the processor 120 in FIG. 1) may perform wireless communication with external electronic devices (e.g., the electronic devices 102 and 104 in FIG. 1), such as a smartphone, a tablet PC, or a personal computer via a first network (e.g., the first network 198 in FIG. 1) or a second network (e.g., the second network 199 in FIG. 1) by using a communication module 290 (e.g., the communication module 190 in FIG. 1). In describing the acoustic device 200 of FIG. 2, a detailed description of components similar to those of the embodiment of FIG. 1 or easily understood through the embodiment of FIG. 1 may be omitted. For example, although omitted in FIG. 2, the acoustic device 200 may include the memory 130, the battery 189, the power management module 188, the audio module 170, the interface 177, and/or the connection terminal 178 of FIG. 1.

[0065] Referring to FIG. 2, the acoustic device 200 may include a processor 220, a communication module 290, a sensor module 276, a microphone unit 250, and/or a speaker unit 255. As will be described with reference to FIG. 3, the acoustic device 200 (e.g., the acoustic device 300 in FIG. 3) may include a main body (e.g., the main body 301 in FIG. 3) and a plurality of (e.g., at least two) ear tips (e.g., the ear tips 302 and 303 in FIG. 3), and the component(s) described with reference to FIG. 2 may be substantially accommodated in the main body 301 of FIG. 3. According to one embodiment of the disclosure, the processor 220 may control at least one other component connected thereto by executing software (e.g., the program 140 in FIG. 1), and may perform wireless communication with external electronic devices (e.g., the electronic devices 102 and 104 in FIG. 1) by using the communication module 290 (e.g., the communication module 190 in FIG. 1). According to an embodiment of the disclosure, information about user settings set in an external electronic device may be received via the communication module 290, and the processor 220 may control the acoustic device 200 (e.g., the speaker unit 255) based on the information received via the communication module 290. In another embodiment of the disclosure, the processor 220 may transmit information about the current operating state to the external electronic device via the communication module 290, and the user may identify the operating state of the acoustic device 200 via the external electronic device.

[0066] According to various embodiments of the disclosure, the speaker unit 255 may receive an electrical signal from the processor 220 to generate sound and output the sound to the outside. For example, the speaker unit 255 may output a multimedia sound or received sound, and may be controlled by the processor 220 with different attributes depending on an operation mode or the type of an ear tip 302 or 303 coupled to the main body 301.

[0067] According to various embodiments of the disclosure, the microphone unit 250 may include a plurality of microphones 250a, 250b, . . . , and 250n, and when including the plurality of microphones 250a, 250b, . . . , and 250n, the microphone unit 250 or the acoustic device 200 may detect the direction of sound or detect external sound. The acoustic device 200 or the processor 220 may suppress or remove noise based on the external sound detected by the microphone unit 250. For example, the processor 220 may attenuate sound other than multimedia sound or received sound output by the speaker unit 255 based on the external sound detected by the microphone unit 250. In some embodiments of the disclosure, in a voice call mode, at least one of the plurality of microphones 250a, 250b, . . . , and 250n may collect a user's voice. In another embodiment of the disclosure, the acoustic device 200 or processor 220 may improve call quality in the voice call mode by enhancing the user's voice and suppressing external sound by using the sound collected via the plurality of microphones 250a, 250b, . . . , and 250n.

[0068] According to various embodiments of the disclosure, the sensor module 276 (e.g., the sensor module 176 in FIG. 1) may generate an electrical signal or data value corresponding to an internal operating state or an external environmental state of the acoustic device 200. In some embodiments of the disclosure, the sensor module 276 may determine whether an ear tip 302 or 303 of FIG. 3 is coupled to the main body 301, identify the ear tip 302 or 303 coupled to the main body 301, and/or determine whether the user wears the acoustic device 200. In an embodiment of the disclosure, the processor 220 may adjust an operation attribute of the speaker unit 255 based on information sensed or detected by the sensor module 276. The operation attribute of the speaker unit 255 may include at least one of a parameter related to an equalizer filter, a parameter related to an equalizer gain, a parameter related to acoustic echo cancellation (AEC), a parameter related to active noise cancellation (ANC), and/or a parameter related to noise reduction.

[0069] According to various embodiments of the disclosure, depending on an ear tip (e.g., one of the ear tips 302 and 303 in FIG. 3) coupled to the main body (e.g., the main body 301 in FIG. 3), the acoustic device 200 (e.g., the acoustic device 300 in FIG. 3) may be one of an open-type earphone or a canal-type earphone, the sensor module 276 may identify an ear tip 302 or 303 coupled to the main body 301, and the processor 220 may control the operation attribute of the speaker unit 255 based on the information identified by the sensor module 276. The configurations of the main body 301 and the ear tips 302 and 303 of the acoustic device 200 will be described with further reference to FIG. 3.

[0070] FIG. 3 is a perspective view illustrating an acoustic device according to an embodiment of the disclosure.

[0071] Referring to FIG. 3, an acoustic device 300 may include a main body 301 and a plurality of ear tips 302 and 303. The main body 301 may accommodate, for example, the processor 220, the communication module 290, the sensor module 276, the microphone unit 250, and/or the speaker unit 255 of FIG. 2, and may include one or more acoustic output ports 311 and 313 or at least one air vent port 315. The acoustic output ports 311 and 313 are ports for outputting or emitting sound generated by, for example, the speaker unit (e.g., the speaker unit 255 in FIG. 2) to the outside, and may include a first output port 311 or a second output port 313. For example, the acoustic output ports 311 and 313 may be generally located on the main body 301 in front of the speaker unit 255. According to an embodiment of the disclosure, the air vent port 315 may be located on the main body 301 behind the speaker unit 255, and make the speaker unit 255 (e.g., a diaphragm) smoothly operate or vibrate. For example, it is possible to allow air to flow into or discharge from the main body 301 so that the internal pressure can be easily changed as the diaphragm of the speaker unit 255 vibrates.

[0072] According to various embodiments of the disclosure, the first output port 311 may function as a path through which most of the sound generated by the speaker unit 255 is output, and the ventilation amount of the first output port 311 may be utilized in sound tuning the mid-tone and/or high-tone range in the sound of the audible frequency band. For example, as the ventilation amount of the first output port 311 increases, the sound pressure of the sound in the mid-tone range may increase. The second output port 313 may be understood as one of air vent ports according to an embodiment of the disclosure, and the ventilation amount of the second output port 313 may be utilized in tuning the sound in the bass-tone range. For example, as the ventilation amount of the second output port 313 increases, the sound pressure of the sound in the bass-tone range may be lowered. In an embodiment of the disclosure, the air vent port 315 may allow a change in the internal pressure of the main body 301 behind the speaker unit 255, and may be utilized to tune the sound in the mid-bass tone range. For example, when the ventilation amount of the air vent port 315 increases, the sound pressure of the sound in the mid-bass tone range may increase. In another embodiment of the disclosure, when the ventilation amount of the air vent port 315 increases, the sound pressure of the sound in the mid-high tone range may decrease.

[0073] According to various embodiments of the disclosure, the acoustic device 300 or the main body 301 may further include a connection terminal 317. The connection terminal 317 may be used, for example, to supply charging power to the acoustic device 300 or to connect the acoustic device 300 to an external electronic device 102 or 104 in a wired manner. Although not illustrated, the acoustic device 300 or the main body 301 may be disposed on or accommodated in a charging cradle in the state of not being worn in a user's body, and the connection terminal 317 may provide electrical connection between the charging cradle and the main body 301.

[0074] According to various embodiments of the disclosure, the acoustic device 300 or the main body 301 may further include at least one sensor 319a or 319b. According to an embodiment of the disclosure, the at least one sensor 319a or 319b may detect the coupled state of the main body 301 and an ear tip 302 or 303 or identify the ear tip 302 or 303 coupled to the main body 301. According to an embodiment of the disclosure, the at least one sensor 319a or 319b may further detect whether the acoustic device 300 is worn in the user's body. The illustrated embodiment exemplifies a configuration in which the acoustic device 300 or main body 301 includes a first sensor 319a for identifying the coupling state of an ear tip 302 or 303 or the coupled ear tip 302 or 303, or a second sensor 319b for detecting whether the acoustic device 300 or main body 301 is worn in the user's body. The first sensor 319a may include, for example, an optical sensor or a magnetic sensor. In an embodiment of the disclosure, when implemented as an optical sensor, the first sensor 319a may be disposed at a position not interfering with the user's body in the state in which the user wears the acoustic device 300. The position at which the first sensor 319a is disposed may be more freely selected when implemented as a magnetic sensor than when implemented as an optical sensor. In another embodiment of the disclosure, the second sensor 319b may include an optical sensor. For example, since the second sensor 319b is disposed at a position that interferes with the user's body in the state in which the user wears the acoustic device 300 and is not exposed to external light, it is possible to detect the worn state of the acoustic device 300.

[0075] According to various embodiments of the disclosure, the ear tips 302 and 303 of the acoustic device 300 may include an elastic material that at least partially comes into contact with the user's body, and may be detachably coupled to the main body 301. One of the ear tips 302 and 303 coupled to the main body 301 may be configured to wear the acoustic device 300 or the main body 301 in the user's body. In an embodiment of the disclosure, of the ear tips 302 and 303, the first ear tip 302 may be coupled to the main body 301 so that the acoustic device 300 operates as an open-type earphone, and of the ear tips 302 and 303, the second ear tip 303 may be coupled to the main body 301 so that the acoustic device 300 operates as a canal-type earphone. For example, the second ear tip 303 may be different from the first ear tip 302 in that the second ear tip 303 includes a structure (e.g., the second coupling portion 303c) that comes into close contact with the inner wall of an ear canal (e.g., the ear canal EI in FIG. 8 or 9). In another embodiment of the disclosure, the main body 301 itself may be utilized as an open-type earphone in the state in which the ear tips 302 and 303 are not coupled.

[0076] According to various embodiments of the disclosure, the first ear tip 302 may include a coupling portion 302a and a first acoustic waveguide portion 302b. The coupling portion 302a may be coupled to surround at least a portion of the main body 301, and may include a first dummy hole 323 corresponding to the second output port 313, a first opening area 325 corresponding to the air vent port 315, a second dummy hole(s) 327 corresponding to the connection terminal 317, and/or sensor holes 329a and 329b corresponding to the sensors 319a and 319b. For example, the coupling portion 302a is coupled to surround at least a portion of the main body 301, and may include openings or holes that expose at least one of acoustic output ports 311 and 313, the air vent port 315, the connection terminal 317, and/or the sensors 319a and 319b disposed in the main body 301 to the outside.

[0077] According to various embodiments of the disclosure, the first dummy hole 323 or the first opening area 325 of the first ear tip 302 may have substantially the same shape and size as the second output port 313 or the air vent port 315 of the main body 301, or may be configured to be larger than the second output port 313 or the air vent port 315 of the main body 301. For example, even if the first ear tip 302 is coupled to the main body 301, the acoustic characteristics of the main body 301 may be substantially the same as design specifications. In an embodiment of the disclosure, since the second dummy hole 327 substantially exposes the connection terminal 317 to the outside, even when the first ear tip 302 is coupled to the main body 301, it may be possible to charge the acoustic device 300 or to connect the acoustic device 300 to an external electronic device 102 or 104 in a wired manner. In another embodiment of the disclosure, when the first ear tip 302 is coupled to the main body 301, the sensor holes 329a and 329b may be disposed to correspond to one of the first sensor 319a and the second sensor 319b. For example, even when the first ear tip 302 is coupled to the main body 301, the first sensor 319a may not substantially detect this, and in this case, the processor (e.g., the processor 120 or 220 of FIG. 1 or 2) may control the acoustic device 300 (e.g., the speaker unit 255 of FIG. 2) according to a first attribute set to correspond to an open-type earphone. In an embodiment of the disclosure, the second sensor 319b of the main body 301 or the sensor hole 329b of the first ear tip 302 that corresponds to the second sensor 319b may be disposed in an area that is obscured by the user's body in the state in which acoustic device 300 is worn in the user's body, whereby the processor 220 may identify or determine whether the acoustic device 300 is worn via the second sensor 319b.

[0078] According to various embodiments of the disclosure, the first acoustic waveguide portion 302b may extend from the coupling portion 302a by a predetermined length, and when the first ear tip 302 is coupled to the main body 301, the first acoustic waveguide portion 302b may be disposed to correspond to the first output port 311. For example, the sound generated by the speaker unit 255 may be output to the outside via the first sound waveguide portion 302b. In the state in which the acoustic device 300 is worn in the user's body, the first acoustic waveguide portion 302b may be at least partially disposed inside the ear canal. For example, the sound generated by the speaker unit 255 may reach the user's ear canal or eardrum while being guided by the first sound waveguide portion 302b.

[0079] According to various embodiments of the disclosure, the second ear tip 303 may include a first coupling portion 303a, a second acoustic waveguide portion 303b, and/or a second coupling portion 303c. The first coupling portion 303a may be coupled to surround at least a portion of the main body 301, and may include a first dummy hole 333 corresponding to the second output port 313 of the main body 301, a second opening area 335 corresponding to the air vent port 315, a second dummy hole(s) 337 corresponding to the connection terminal 317 and/or an optical pattern 339a or a sensor hole 339b corresponding to the sensors 319a and 319b. For example, the first coupling portion 303a is coupled to surround at least a portion of the main body 301, and may include openings or holes that expose at least one of acoustic output ports 311 and 313, the air vent port 315, the connection terminal 317, and/or the sensors 319a and 319b disposed in the main body 301 to the outside. It is noted that, since the dummy holes 333 and 337 corresponding to the second output port 313 or the connection terminal 317 may provide substantially the same functions at the dummy holes 323 and 327 of the first ear tip 302, in the description of the embodiment of FIG. 3, the same names are given, but reference numerals in the drawings are separately assigned.

[0080] According to various embodiments of the disclosure, the first dummy hole 333 of the second ear tip 303 may have substantially the same shape and size as the second output port 313 of the main body 301 or may be configured to be larger than the second output port 313 of the main body 301. According to the acoustic tuning or design of an actual product, the first dummy hole 333 may have a smaller size than the second output port 313. In an embodiment of the disclosure, the second opening area 335 may have a smaller size than the air vent port 315 or the first opening area 325. For example, when the second ear tip 303 is coupled, the area in which the air vent port 315 is exposed to the external space may be smaller than when the first ear tip 302 is coupled. In some embodiments of the disclosure, the air vent port 315 may be substantially closed even though the second opening area 335 is provided. For example, when the second ear tip 303 is coupled, the air vent port 315 may be exposed to the external space in an area smaller than its actual size. According to an embodiment of the disclosure, when comparing the case where the first ear tip 302 is coupled to the main body 301 and the case where the second ear tip 303 is coupled to the main body 301, when the second ear tip 303 is coupled, the internal pressure change behind the speaker unit 225 (e.g., a diaphragm) inside the main body 301 may be suppressed due to the size or shape of the second opening area 335. In another embodiment of the disclosure, since the second ear tip 303 is coupled to the main body 301, it is possible to provide the shape or characteristics of a canal-type earphone, and the sound pressure loss in the mid-bass tone range in an actual use environment may be smaller than that in an open-type earphone. For example, even if the change in the internal pressure of the main body 301 is somewhat suppressed and the sound pressure of the mid-bass tone sound output from the speaker unit 255 becomes smaller than the design specification, the sound in the mid-bass tone range perceived by the user may be substantially the same as the design specification of the main body 301 or the speaker unit 255.

[0081] According to various embodiments of the disclosure, since the second dummy hole 337 substantially exposes the connection terminal 317 to the outside, even when the second ear tip 303 is coupled to the main body 301, it may be possible to charge the acoustic device 300 or to connect the acoustic device 300 to an external electronic device 102 or 104 in a wired manner. In another embodiment of the disclosure, the optical pattern 339a may be provided on the inner peripheral surface of the first coupling portion 303a to be disposed to correspond to the first sensor 319a when the second ear tip 303 is coupled to the main body 301. For example, the first sensor 319a may be an optical sensor, and by detecting the optical pattern 339a, it is possible to detect or identify that the second ear tip 303 is coupled to the main body 301. When it is detected that the second ear tip 303 is coupled to the main body 301, the processor 220 may control the acoustic device 300 (e.g., the speaker unit 255 in FIG. 2) according to a second attribute different from the first attribute, for example, an attribute set to correspond to a canal-type earphone. In another embodiment of the disclosure, when the first sensor 319a is a magnetic sensor, a magnet may be disposed at a position where the optical pattern 339a is illustrated, and the optical pattern 339a may be omitted.

[0082] According to various embodiments of the disclosure, the second acoustic waveguide portion 303b may extend from the first coupling portion 303a by a predetermined length, and when the second ear tip 303 is coupled to the main body 301, the second acoustic waveguide portion 302b may be disposed to correspond to the first output port 311. For example, the sound generated by the speaker unit 255 may be output to the outside via the second sound waveguide portion 303b. When the acoustic device 300 is worn in the user's body, the second acoustic waveguide portion 303b is at least partially disposed inside the ear canal. Thus, the sound generated by the speaker unit 255 is capable of reaching the user's ear canal or eardrum under the guidance of the second acoustic waveguide portion 303b.

[0083] According to various embodiments of the disclosure, the second coupling portion 303c extends from the outer peripheral surface of the second acoustic waveguide portion 303b, and may be configured to come into close contact with the inner wall of the user's ear canal. In an embodiment of the disclosure, when the acoustic device 300 in which the second ear tip 303 is coupled to the main body 301 is worn in the user's body, the second acoustic waveguide portion 303b and/or the second coupling portion 303c may substantially isolate the space between the first output port 311 and the user's eardrum from the outside of the ear canal. For example, the sound generated by the speaker unit 255 may reach the user's eardrum without substantial loss of sound pressure. Since the sound generated from the speaker unit 255 is able to reach the user's eardrum without loss of sound pressure, even if the main body 301 or the speaker unit 255 has output that is slightly lower than the design specification in the state in which the second ear tip 303 is coupled to the main body 301, the sound pressure perceived by the user may be substantially the same as the design specification.

[0084] FIG. 4 is view illustrating graphs representing frequency response characteristics of an acoustic device according to an embodiment of the disclosure.

[0085] Referring to FIG. 4, the graph indicated by “0” represents a frequency response characteristic when the acoustic device 300 operates as an open-type earphone, for example, a frequency response characteristic of the main body 301 itself of FIG. 3 or in the state in which the first ear tip 302 is coupled to the main body 301. The graph indicated by “CO” in FIG. 4 represents a frequency response characteristic in the state in which the entire area of the air vent port 315 is substantially open through the second opening area 335 while the second ear tip 303 of FIG. 3 is coupled to the main body 301. The graph indicated by “CH” in FIG. 4 represents a frequency response characteristic in the state in which approximately half of the air vent port 315 is closed by the second ear tip 303 and the other half of the air vent port 315 is opened through the second opening area 335 while the second ear tip 303 of FIG. 3 is coupled to the main body 301. The graph indicated by “CC” in FIG. 4 represents a frequency response characteristics in the state in which the air vent port 315 is substantially closed while the second ear tip 303 of FIG. 3 is coupled to the main body 301. In an embodiment of the disclosure, the graph indicated by “0” may be understood as substantially representing the acoustic characteristic of the acoustic device 300 according to the design specification of the main body 301 or the speaker unit 255.

[0086] As illustrated in FIG. 4, in an acoustic frequency band of approximately 400 to 500 Hz or higher, a significant difference in frequency response characteristics depending on the degree of opening or exposure of the air vent port 315 may not occur. It can be seen that with sound in the mid-bass tone range of about 400 Hz or less, in the canal-type earphone, when the second ear tip 303 is coupled, the frequency response characteristics depending on the degree of opening of the air vent port 315 are variously changed. For example, when the second ear tip 303 is coupled to an open-type earphone (e.g., the main body 301 in FIG. 3) so that the acoustic device is used as a canal type, the frequency response characteristic most similar to the design specification of the main body 301 or the speaker unit 225 may be implemented in the state in which approximately half of the air vent port 315 is exposed. As described above, the acoustic device 300 according to various embodiments of the disclosure may be used as an open-type earphone with the main body 301 itself, and may provide substantially the same acoustic characteristics as the design specification of the main body 301 while being used as a canal-type earphone by using an ear tip (e.g., the second ear tip 303) coupled to the main body 301.

[0087] FIG. 5 is an enlarged perspective view of a portion of the main body of an acoustic device according to an embodiment of the disclosure.

[0088] FIG. 6 is an enlarged perspective view of a portion of a second ear tip of an acoustic device according to an embodiment of the disclosure.

[0089] FIG. 7 is a circuit diagram illustrating an ear tip coupling detection circuit of an acoustic device according to an embodiment of the disclosure.

[0090] Referring to FIGS. 5, 6, and 7, the acoustic device of the embodiment may be substantially the same as the acoustic device 300 of FIG. 3, and may be different from the embodiment of FIG. 3 in the configuration including the electrodes 441 and 443 or the conductive pattern 445 for identifying whether or not an ear tip 302 or 303 is coupled to the main body 301 or identifying the ear tip 302 or 303 coupled to the main body 301. Accordingly, in the detailed description made with reference to FIGS. 5 and 6, the configuration related to identifying whether an ear tip 302 or 303 is coupled or the type of the coupled ear tip 302 or 303 will be described. Referring to FIGS. 5 and 6, the acoustic device 300 may include a pair of electrodes 441 and 443 disposed on a body 301 or a conductive pattern 445 provided on the inner peripheral surface of the second ear tip 303. The conductive pattern 445 may not be provided in the first ear tip 302. By using the electrodes 441 and 443 and the conductive pattern 445, the acoustic device 300 or the processor 220 may identify whether an ear tip 302 or 303 is coupled and the ear tip 302 or 303 coupled to the main body 301. In this case, one of the sensors 319a and 319b of FIG. 3, for example, the first sensor 391a, may be omitted.

[0091] According to various embodiments of the disclosure, of the electrodes 441 and 443, the first electrode 441 may be connected to a general-purpose input/output port (GPIO port) via a first resistive element R1, and the second electrode 443 may be connected to a ground via a second resistive element R2. The conductive pattern 445 may be configured to short-circuit the first electrode 441 and the second electrode 443 when the second ear tip 303 is coupled to the main body 301. In an embodiment of the disclosure, in the state in which a first voltage is applied to the first resistive element R1, when the ear tips 302 and 303 are not coupled to the main body 301 or the first ear tip 302 is coupled to the main body 301, the first voltage may be output to the general purpose input/output port (GPIO port). For example, in the state in which the first electrode 441 and the second electrode 443 are not short-circuited, the voltage of a signal applied to the first resistive element R1 is output to the general-purpose input/output port (GPIO port). In this case, the processor 220 may control the speaker unit 225 based on a first attribute. In another embodiment of the disclosure, when the second ear tip 303 is coupled to the main body 301 in the state in the first voltage is applied to the first resistive element R1, the first electrode 441 and the second electrode 443 may be short-circuited to each other, and a second voltage lower than the first voltage may be output to the general-purpose input/output port (GPIO port). In this case, the processor 220 may control the speaker unit 225 with the second attribute corresponding to the canal-type earphone. As described with reference to FIG. 4, the acoustic characteristics of the acoustic device 300 operating as the canal-type earphone may be tuned depending on the exposure degree of the air vent port 315. In some embodiments of the disclosure, the acoustic characteristics may be tuned according to the attribute controlling the speaker unit 255, and through a combination of the attribute controlling the speaker unit 255 and the degree of exposure of the air vent port 315, the acoustic characteristics of the speaker unit 255 or the acoustic device 300 may be tuned.

[0092] FIG. 8 is a view illustrating a state in which an acoustic device is worn in a user's body in an open-type state according to an embodiment of the disclosure.

[0093] FIG. 9 is a view illustrating a state in which an acoustic device is worn in a user's body in a canal-type state according to an embodiment of the disclosure.

[0094] Referring to FIGS. 8 and 9, in the state of being worn in the user's body, the main body 301 or the ear tips 302 and 303 are generally located in an area or space defined by the user's pinna EO, and a portion (e.g., the acoustic waveguide portions 302b and 303b in FIG. 3) may be disposed inside the ear canal EI. In the state of being worn in the user's body, the relative magnitude of the sound pressure RP reflected from the inside of the ear canal compared to the sound pressure OP output by the acoustic device 300 may vary. For example, if the sound pressure OP output by the acoustic device 300 is the same when operating as an open-type earphone and when operating as a canal-type earphone, the sound pressure RP reflected from the inside of the ear canal may be higher when the acoustic device 300 operates as the canal-type earphone. It may be understood that this is due to the fact that, in the state of being worn in the user's body, the open-type earphone has a structure that allows more pressure to outflow (LP) from the inside of the ear canal than the canal-type earphone.

[0095] According to various embodiments of the disclosure, the microphone unit 250, for example, at least one of the microphones 250a, 250b, . . . , and 250n of FIG. 2 may detect the sound pressure (RP) or sound reflected from the inside of the ear canal. The acoustic device 300 or the processor 220 may identify whether the current operating state is an open-type earphone state or a canal-type earphone state by detecting the sound pressure (RP) or sound reflected from the inside of the ear canal. For example, based on the relative difference between the output sound pressure (OP) and the sound pressure (RP) reflected from the inside of the ear canal, the acoustic device 300 or the processor 220 may identify the current operating state or the ear tip 302 or 303 coupled to the main body 301. In some embodiments of the disclosure, the acoustic device 300 or the processor 220 may identify an ear tip 302 or 303 coupled to the main body 301 based on the relative differences in sound pressure, and may control the speaker unit 225 by using an attribute corresponding to the identified ear tip. When set to identify the ear tip 302 or 303 coupled to the main body 301 based on the relative difference in sound pressure, the acoustic device 300 or the main body 301 may not include one of the sensors 319a and 319b of FIG. 3 (e.g., the first sensor 391a) or the electrodes 441 and 443 and the conductive pattern 445 of FIGS. 5 and 6. In another embodiment of the disclosure, although set to identify an ear tip 302 or 303 coupled to the main body 301 based on the relative difference in sound pressure, the acoustic device 300 or the processor 220 may include one of the first sensor 319a of FIG. 3 or the electrodes 441 and 443 of FIG. 5, and when including the electrodes 441 and 443 in FIG. 5, the acoustic device 300 or the processor 220 may include a conductive pattern (e.g., the conductive pattern 445 in FIG. 6) provided on the second ear tip 303.

[0096] FIG. 10 is a flowchart illustrating a method of an acoustic device according to an embodiment of the disclosure.

[0097] In describing the control method 400 of the acoustic device 300 according to various embodiments of the disclosure, the above-described embodiments may be referred to together.

[0098] Referring to FIG. 10, the control method 400 of the acoustic device 300 may include operation 401 of identifying an ear tip 302 or 303, and operation 402a or 402b of controlling the speaker unit 255 with an attribute predetermined based on the identified ear tip 302 or 303. For example, the acoustic device 300 or the processor 220 may be configured to identify whether an ear tip 302 or 303 is coupled to the main body 301 or the ear tip 302 or 303 coupled to the main body 301 (e.g., operation 401), and control the speaker unit 255 with an attribute predetermined based on the identified ear tip 302 or 303 (e.g., operation 402a or operation 402b).

[0099] According to various embodiments of the disclosure, in operation 401, the processor 220 may identify whether an ear tip 302 or 303 is coupled to the main body 301 or the ear tip 303 or 303 coupled to the main body 301 by using one of the sensors 319a and 319b of FIG. 3, the electrodes 441 and 443 of FIG. 5, and/or the microphone unit 250. In some embodiments of the disclosure, the first sensor 319a of FIG. 3 may be an optical sensor or a magnetic sensor, and the ear tips 302 and 303 may include an identifier detectable by first sensor 319a. The “identifier” may be, for example, an optical pattern or a magnet. In an embodiment of the disclosure, the first ear tip 302 corresponding to the open-type earphone may not include the identifier, and the second ear tip 303 corresponding to the canal-type earphone may include the identifier. For example, when the identifier is not detected, the processor 220 may determine that the ear tips 302 and 303 are not coupled to the main body 301 or that the first ear tip 302 is coupled. In another embodiment of the disclosure, when the second ear tip 303 is coupled to the main body 301, the processor 220 may detect or determine that the second ear tip 303 is coupled to the main body 301 via the first sensor 319a. In another embodiment of the disclosure, when the electrodes 441 and 443 of FIG. 5 are disposed on the main body 301, the identifier may be replaced with the conductive pattern 445 of FIG. 6. For example, when the electrodes 441 and 443 are short-circuited by the conductive pattern 445, the processor 220 may identify or determine that the second ear tip 303 is coupled to the main body 401.

[0100] According to various embodiments of the disclosure, when it is determined in operation 401 that the acoustic device 300 is able to operate as an open-type earphone, the processor 220 may control the speaker unit 255 with the first attribute of operation 402a. In some embodiments of the disclosure, when determining that the acoustic device 300 is able to operate as an open-type earphone, the processor 220 may output a voice that is capable of notifying the user that the acoustic device 300 is currently operating as the open-type earphone via the speaker unit 255. In operation 401, when determining that the acoustic device 300 is able to operate as a canal-type earphone, the processor 220 may control the speaker unit 255 with the second attribute of operation 402b. In some embodiments of the disclosure, when determining that the acoustic device 300 is able to operate as a canal-type earphone, the processor 220 may output a voice that is capable of notifying the user that the acoustic device 300 is currently operating as the canal-type earphone via the speaker unit 255. The first attribute and the second attribute may include at least one of a parameter related to an equalizer filter, a parameter related to an equalizer gain, a parameter related to acoustic echo cancellation (AEC), a parameter related to active noise cancellation (ANC), and/or a parameter related to noise reduction. In some embodiments of the disclosure, the speaker unit 255 may have a higher output in the mid-bass region when controlled with the first attribute than when controlled with the second property.

[0101] In some embodiments of the disclosure, the parameters listed above may be different depending on the type of sound output from the acoustic device 200 or 300, as in a multimedia playback mode or a voice call mode. For example, for convenience of description, the attribute of controlling the speaker unit 255 will be described by diving it into a first attribute and a second attribute depending on the ear tip 302 or 303 coupled to the main body 301. However, various embodiments of the disclosure are not limited thereto, and the attributes for controlling the speaker unit 255 may be variously selected depending on the type of sound output from the acoustic device 300 or the operation mode of an external electronic device 102 or 104 interlocked with the acoustic device 300. In another embodiment of the disclosure, when the acoustic device 300 is linked with an external electronic device 102 or 104, such as a smartphone, for example, when a sound source is substantially provided from the external electronic device 102 or 104, the acoustic device 300 or the processor 220 may transmit information about the current operation mode or operation state to the external electronic device while performing wireless communication by using the communication module 290. The user may identify the information transmitted from the acoustic device 300 via the external electronic device 102 or 014 and, if necessary, adjust the operating state of the acoustic device 300 by using the external electronic device 102 or 104.

[0102] According to various embodiments of the disclosure, depending on the ear tip 302 or 303 coupled to the main body 301, the acoustic device 300 may operate as an open type or a canal type, so that the user may also use a single acoustic device 300 in a type that meets the environment of use or the user's needs. By adjusting the exposed area of the air vent port 315 or changing the control attributes of the speaker unit 255 depending on whether the ear tip 302 or 303 is of the open type or the canal type, the user may be provided with sound of substantially the same sound quality regardless whether the ear tip is of the canal type or the open type. For example, a user may conveniently use the acoustic device 300 suitable for the environment of use without the economic burden or inconvenience of owning or carrying a plurality of acoustic devices.
